在中国原子能科学研究院提议的串列加速器升级工程中,将建造一台100 MeV强流负氢回旋加速器。作为必要的预先研究,我们计划研制其中心区模型,磁钢度为0.455 T·m。该中心区模型可将负氢离子加速到10 MeV,除了作为强流回旋加速器的先进技术研究外,还可用于生产PET常用的超短寿命放射性核素:~(11)C、~(13)N、~(15)O和~(18)F,由于它的高流强,将会有更高的放射性核素产额,预计一台这样的加速器,将能满足国内任何一个城市对~(18)F的需求。
In the proposed tandem accelerator upgrade project of China Institute of Atomic Energy, a 100 MeV high-current negative cyclotron will be built. As a necessary prior study, we plan to develop a model of its central area with a degree of magnet of 0.455 T · m. The central model accelerates the negative hydrogen ions to 10 MeV. In addition to its advanced technology as a high-intensity cyclotron, it can also be used to produce ultra-short-lived radionuclides commonly used in PET: ~ (11) C, ~ (13) N, ~ (15) O and ~ (18) F, due to its high flow rate, will have a higher radionuclide yield. It is expected that one such accelerator will meet the requirements of any city in China. F’s needs.
